Felony charges were filed Friday against two men and a cattle ranch in connection with the fire. Jose Cabrera, 38, of Santa Ynez; Santiago Cervantes, 46, of Santa Maria; and Rancho La Laguna LLC were charged with three counts each of recklessly causing a fire with great bodily injury to three victims and one count of recklessly causing a fire of a structure or forest.

The 200-acre blaze was fanning out in several directions about 10 miles east of Santa Clarita, Forest Service spokesman Stanton Florea said.

Six air tankers, three helicopters and several ground crews were fighting the fire. Florea said the cause was under investigation. Lightning strikes had been observed.

A 125-acre wildfire burned dense brush in San Bernardino National Forest at the east end of Big Bear Lake yesterday and forced the closure of state Route 18 but did not threaten any homes. The blaze was likely sparked by lightning Saturday, officials said.

Also yesterday, a 22-acre brush fire scorched two homes in Corona in Riverside County. No one was injured. The cause of the blaze had not been determined.
